BRAKE-BEAM FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed December 26,1905. Renewed August 29, 1906. Serial No. 332,410.

T0 at whom it may concern:

. Be it known that I, SETH A. CRoNE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Brake- Beams for Railway-Cars, of which the following is a specification.

The invention relates to improvements in brake-beams for railway-cars and it consists in the novel features and construction hereinafter described, and particularly pointed out in the claims.

Brake-beams of the class to which my invention pertains comprise a rolled body-beam of suitable length, brake-heads of suitable construction on the ends thereof, and a fulcrum for the brake-lever; and my invention has for its object to produce a novel fulcrum for use in such beams, said fulcrum being eflicient and capable of being firmly and quickly applied to the beam.

My present invention pertains more especially to improvements in the class of brakebeam fulcrums described and claimed in Letters Patent of the United States numbered, respectively, 720,676, dated February 17, 1903, and 731,668, granted June 23, 1903; and its object is to produce a forged-metal fulcrum having its parts bent into the required shape, the parts of the fulcrum while being given such shape not being materially stretched or weakened, my invention contemplating the manufacture of the fulcrum without during the bending operations stretching or in any other manner weakening or unduly punishing the same.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure 1 is a detached top view of a fulcrum constructed in accordance with and embodying the invention. Fig. 2 is an outer end view of same, taken from the right-hand end of Fig. 1; and Fig. 3 is a transverse section through a brake-beam having the fulcrum applied thereto, the fulcrum being shown in side elevation.

In the drawings, 10 designates a portion of the usual body-beam, and 11 the novel fulcrum of my invention, which is applied centrally on one edge of the beam and in the form shown is in one integral bar of forged metal folded at its center to form the angularly-disposed parallel side members 12 13,

which are apertured, as at 14, to receive the pin for the brake-lever (not shown) and beyond which the ends of the bar are carried outwardly in opposite directions from said sides and from the longitudinal center line 21 of the fulcrum and on inclined lines transversely of the beam 10, Fig. 2, forming curved flanges 15, and then bent to form flanges 16 17, which respectively engage the flange and web of the beam 10 and the latter of which are apertured, as at 18, to receive rivets 19, by which the fulcrum may be secured to said beam. The formation of the flanges 15 by bending the ends of the metal bar outwardly in a direction from, but in line with, the angularly-disposed sides 12 13 and from each other and then bending the remaining portions of said ends to form the flanges 16 17 results in the ends of the bar being carried out of transverse alinement with each other, as shown in Figs. 1 and 2, whereby three purposes are attamed, the first being that the flanges 15, 16, and 17 are formed. conveniently and without unduly stretching or weakening the metal, the second being that the flanges 17 become so separated that two rivets are required to secure them to the beam and that, therefore, any tendency of the fulcrum to swivel on its securing-rivet (as when one rivet only is used, as shown in the aforesaid patents) is prevented, and the third being that by the spreading apart or separation of the flanges 17 the fulcrum is enabled to resist greater strains and when made in one piece or in two pieces secured together at the outer end 20 of the fulcrum may be more readily applied upon th beam preparatory to riveting.

The fulcrum shown will be made of forged metal and preferably from an integral merchant-bar of proper length and width, so that the entire fulcrum may be in a single piece;

but it is obvious'that with less advantage the fulcrum side members may be in separate pieces and, if desired, riveted together at the outer end 20 of the fulcrum in the several ways known to the artas, for illustration, as shown in Patent No. 720,677, dated February 17, 1903.

In prior patents showing forged-metal fulcrums the flanges 17 17 have been parallel or nearly parallel with each other, considered transversely on vertical lines through the beam 10, and this has resulted in two features, the first being that a single rivet is used to secure the fulcrum to the beam, wherebythe tendency of the fulcrum to swivel on the rivet is not effectually overcome, and the second being that the end portions of the bar are carried so abruptly from the diagonal sides 12 13 and inwardly toward a longitudinal center line through the fulcrum that the metal becomes stretched on diagonally opposite edges or that the operation of offsetting .the ends of the bar in opposite directions, as shown in the aforesaid Patent No. 731,668, must be resorted to to prevent that result.

4 In accordance with my present invention I secure the fulcrum to the beam by two inde pendent separated rivets 19, and I avoid both undue stretch of the metal and the necessity of offsetting the ends of the bar by carrying the ends of the bar outwardly fromthe diagonal sides and from a longitudinal center line through the fulcrum instead of inwardly towardsuch center line, as is necessary if the flanges 17 are to be opposite to each other on the opposite sides of the beam.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A brake-beam fulcrum of forged metal having the diagonally-disposed side members from which the inner end portions of the fulcrum extend outwardly and from a center line through the fulcrum, forming flanges 15, and thence inwardly in a direction transversely of the beam to form the flanges 16, 17 to engage the flange and web of the beam, whereby the said flanges 17 become spread apart substantially as set forth.

2. A brake-beam fulcrum of forged metal in one integral folded bar having the diagonally-disposed side members from which theinner end portions of the fulcrum extend outwardly and from a center line through the fulcrum, forming" flanges 15-, thence bent inwardl-yin a direction transversely of the beam to form the flanges 1 6-, 1 7 to engage the flange and web of the beam, whereby the said flanges 17 become spread apart; substantially as set forth.

Signed at New York city, in the county of New York and State of New York, this 23d day of December, A.. D.. 1905.
